ETC needs to be reinstalled and reactivated after falling off. The installation process for the ETC device is as follows: Upon receiving the device, first check if the ETC card and the electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU. A red light will briefly turn on, and the OLED screen will display "Tag Invalid" or "Please Insert Card," indicating the device is functioning properly. Clean the front windshield, ensuring the surface is smooth, clean, and dry. Then peel off the adhesive backing of the OBU and stick it to the installation position. Press firmly for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front facing the driver and the back facing the windshield. The chip should be inserted into the OBU device. Method to activate the ETC device: Insert and remove the ETC card twice in succession until the electronic tag screen displays "Bluetooth On." If the screen shows "Tag Invalid" when inserting and removing twice without the electronic tag attached, this is normal and does not affect activation. Alternatively, press the button on the top of the electronic tag to enable Bluetooth. Turn on your phone's Bluetooth and open the corresponding mobile app (usually, a download QR code is provided on the electronic tag). Navigate to the device activation interface. Click "Connect Device" and wait patiently for the "Connection Successful" prompt. Once connected, upload a photo of the vehicle's front to complete activation.

Why No One Installs Car Bumper Guards?

Car bumper guards are not widely installed because they only provide protection against minor scratches and are ineffective in major collisions. Below are some key points about car bumper guards: 1. Function: Car bumper guards can enhance the vehicle's lines and dynamic appearance, serving a decorative purpose; they also help protect the vehicle's sides from scratches or impacts caused by external objects. 2. Disadvantages: The adhesive layer of car bumper guards is often too thick, leading to poor adhesion; the glue has weak bonding properties, resulting in insecure and non-durable attachment. When bumper guards age, crack, or fall off, they should be promptly replaced with new ones.

What are the components of car wax?

Car wax is primarily composed of natural wax or synthetic wax. Here is an introduction to car wax: 1. Introduction: Car wax is a traditional automotive paint surface maintenance product. It works by penetrating into the gaps of the paint surface to smooth the surface, thereby enhancing the glossiness. 2. Functions: (1) Waterproofing effect: Car wax can reduce the adhesion of water droplets on the car body paint surface by 60%-90%, and it can also further flatten the remaining water droplets, making them flatter, thereby reducing dark spots, erosion, and damage caused by the focusing effect of intense sunlight on water droplets. (2) High-temperature resistance: The high-temperature resistance of car wax effectively reflects incident light from different directions, preventing the light from penetrating the clear coat and causing the base coat to age and discolor, thus extending the lifespan of the paint surface. (3) UV protection: UV-resistant car wax fully considers the characteristics of ultraviolet rays, reducing their damage to the car surface.

Why does an automatic transmission car experience jerking at low speeds?

There are three possible reasons for jerking sensations during low-speed driving in an automatic transmission car: 1. Carbon buildup: Excessive carbon deposits in the throttle body, fuel injectors, or intake manifold can cause various malfunctions, including jerking sensations. Regular carbon cleaning is recommended. 2. Fuel quality: Poor-quality fuel that doesn't burn completely. 3. Spark plug or ignition coil failure: Malfunctions in spark plugs or ignition coils can cause cylinder misfires. In such cases, it's necessary to visit a repair shop for inspection and timely maintenance to prevent potential safety hazards.

Does an automatic transmission car consume more fuel the slower it drives?

An automatic transmission car does indeed consume more fuel the slower it drives. Whether a car saves fuel or consumes more depends on road conditions, load, and speed. Driving slowly does not necessarily mean saving fuel, nor does driving fast necessarily mean consuming more fuel. It is related to the overall operating condition of the vehicle, such as high friction coefficients in some connections, overloaded weight, and the quality of the road conditions. Following the instructions in the car manual is the most fuel-efficient approach. Below is the classification method for car engine oil grades: 1. AB series: Oil for gasoline and light-duty diesel engines. 2. C series: Oil suitable for catalyst-equipped engines. 3. E series: Oil for heavy-duty diesel engines.
